Use the V4L2 core locking system instead of rolling your own. Switch to the vb2 fop and ioctl helpers to get rid of a lot of code. This also made it easy to add VB2_READ to the DMA modes, since you get read() for free with vb2 and these helpers. Finally remove the users field: this information is also available from the core framework, no need to keep track of it in the driver. Signed-off-by:

Now that this driver uses v4l2_fh, it is trivial to add support for control events. Again, this fixes a v4l2-compliance failure. Signed-off-by:

Use struct v4l2_fh to represent a filehandle. This fixes the missing g/s_priority handling of this driver that v4l2-compliance complained about. Signed-off-by:

No controls were reported, even though the ov7670 does have controls. Two reasons for this: the v4l2_ctrl_handler_init() call must come before the ov7670 is loaded (otherwise the ov7670 won't know that its controls should be added to the bridge driver), and the v4l2_ctrl_handler_free() call at the end should only be called if the ret value is non-zero (otherwise you would just free all the controls that were just added).

Running v4l2-compliance on my usbtv stick revealed two failures: 1) Correct handling of CREATE_BUFS in usbtv_queue_setup was missing. Added this. 2) The sequence counter wasn't reset to 0 when starting streaming. Signed-off-by:

Currently vb2 core acquires mmap_sem just around call to __qbuf_userptr(). However since commit f035eb4e (videobuf2: fix lockdep warning) it isn't necessary to acquire it so early as we no longer have to drop queue mutex before acquiring mmap_sem. So push acquisition of mmap_sem down into .get_userptr and .put_userptr memops so that the semaphore is acquired for a shorter time and it is clearer what it is needed for. Signed-off-by:

Changed the rounding calculation for hblank and hsync to match it to equations in cvt and gtf standards. In cvt calculation, hsync needs to be rounded down. In gtf calculations, hblank needs to be rounded to nearest multiple of twice the cell granularity and hsync needs to be rounded to the nearest multiple of cell granularity.

Changed the rounding offsets used in vsync_bp calculation in cvt and gtf timings. The results for vsync_bp should now match with results from timing generator spreadsheets for cvt and gtf standards. In the vsync_bp calculation for cvt, always round down the value of (CVT_MIN_VSYNC_BP / h_period_est) and then add 1. It thus, reflects the equation used in timing generator spreadsheet. Using 1999999 as rounding offset, could pontentially lead to bumping up the vsync_bp value by extra 1. In the vsync_bp calculations for gtf, instead of round up or round down, round the (CVT_MIN_VSYNC_BP / h_period_est) to the nearest integer.

VIDEOBUF2_DMA_SG cannot be enabled manually by the user, it's always selected automatically by drivers that need it. Several of those drivers already have an explicit dependency on HAS_DMA. Make VIDEOBUF2_DMA_SG depend on HAS_DMA. This makes it easier to find drivers that select VIDEOBUF2_DMA_SG without depending on HAS_DMA, as Kconfig will give a warning. Signed-off-by: -

When using VIDIOC_G_EDID there is a special case where start_blocks and blocks are both set to 0. In that case the driver just has to set blocks to the total number of available blocks and return 0. Even though the drivers do this right and v4l2-compliance tests for it, it turned out not to be documented in the spec. Fix this. Signed-off-by:

If pci_disable_device() isn't called when the driver is removed, then the next time when it is loaded the irq isn't found. I'm pretty sure this used to work in the past, but calling pci_disable_device() is clearly the correct method and this makes it work again. Signed-off-by:
